This report presents findings of a bedrock geological mapping project carried out in 2003 in the Ferguson Lake area, located about 200 kilometres west of Rankin Inlet, Nunavut. The project was initiated to provide better understanding of the geology & deformation history of the area and to put a local nickel-copper-platinum group element deposit into a regional context. The main part of the report describes the rock units exposed in the area (metamorphosed supracrustal rocks and intrusive rocks) and the area's structural elements (gneissosity, folds, foliation, shear zones, faulting). An attempt is then made to correlate the deformational features observed in the area with those documented by other researchers. Finally, implications of the findings for the timing of mineralization are briefly discussed.

This report is part of an ongoing study to characterize both sequence stratigraphy and chronostratigraphy of the Baker Lake Basin, Nunavut. The investigators examined well-exposed segments of the basin in detail, emphasizing sequence stratigraphic analysis to identify genetic packages of strata related to tectonically controlled basin-filling rhythms. Three sections exposed at the western edge of Thirty Mile Lake have been measured and correlated, yielding data on five depositional sequences. After an introduction on the geologic setting of the study area, the report provides facies assemblage descriptions and interpretations of the five depositional sequences of the lower Baker Lake Group. Finally, the accommodation (or space made available for a sedimentary system to fill) cycle in the basin is discussed and conclusions are drawn regarding the subsidence mechanism in the basin.

This report presents results of geologic fieldwork that updates mapping in the Sealhole-Fitzpatrick lakes area west of Hudson Bay, Nunavut, with a focus on the paleogeographic and structural evolution of the Henik, Montgomery, and Hurwitz groups. Along with descriptions of the Archean to Paleoproterozoic rocks and their stratigraphic relationships, the report discusses the area's geologic structure and the evidence for Archean and Paleoproterozoic deformation.
